Can someone please tell me how many block will require to fence a 3 plot of land

and how much is per block?

The number of blocks to fence 3 plots of land depends the followings:

1. how high you want the fence to go.Height can vary from 6ft to 8ft.

2. Measurement of the plots. some plots are 60x120 or 50x100 or different [i have seen plots 100x150]

3. How many level of blocks will be required for the foundation. This can sometimes depend on the topography of the land. Some land may be sloppy and requires up to 5 levels of foundations.

With all that said, 3 plots will be about 20,000 blocks to fence.[ Blocks can cost about N120-N140 depending on quality.]

I hope it helps.
